Mesut Ozil scored a second-half hat-trick as Arsenal eased past Ludogorets 6-0 at the Emirates Stadium to maintain their slender lead at the top of Group A.

Yannick Carrasco scored the only goal of the game as Atletico Madrid maintained their 100% record in Group D with a 1-0 win at Rostov.

Group B leaders Napoli saw their 100% record brought to an end as two Vincent Aboubakar goals helped Besiktas to a surprise 3-2 win in Italy.
